Process Extract Association

[OpenDataAlex]

When ProcessTracker finds extracts need to have method to associate the process run to the extracts and change their status. Finders shouldn't necessarily do this by default though that would be an obvious place for it.

Adding a new extract status type for use specifically with ProcessTracker finding extracts ('retrieved'). This is just to show that the process retrieved the extract, even if nothing more was done with it. Further extract status changes will replace this status anyway. Finders will associate the process with the extract putting the new status type in the extract_process_tracker table.

Changed my mind - getting rid of new type and just adding new helper method on ProcessTracker to bulk change extract status, which will utilize the method on ExtractTracker to keep the extract and extract_process records updated.
